-- @testpoint: opengauss关键字position(非保留)，作为函数名,部分测试点合理报错

--关键字不带引号-合理报错
drop function if exists position(i integer);
create function position(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;
/
--关键字带双引号-成功
drop function if exists "position"(i integer);
create function "position"(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;
/
--关键字带单引号-合理报错
drop function if exists 'position'(i integer);
create function 'position'(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;
/
--关键字带反引号-合理报错
drop function if exists `position`(i integer);
create function `position`(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;
/
--清理环境
drop function if exists "position"(integer);
